Interesting. Because if you think about it, the rest of this trip is pretty much all down wind.

So if you had canvas made that you could deploy off you boat to the paravane booms you good sail along nicely I would think, wing on wing so to speak.

Yup, I get that. Still have a foot firmly planted in the last century, I guess.

My wife & I went on sea kayak trips "back in the day" where nobody would hear from us for two months. Felt good. We carry a Spot Messenger now, and I don't know if it allows the same sense of remote wilderness we used to get. Might be getting too touchy-feely or philosophical...

My guess is that would be a S-L-O-W trip downwind! Wing and wing downwind is a slow point of sail on a slippery sailboat! I can't imagine trying to make real distance on a 42' trawler that way...

Well if you're out of fuel I doudt you be complaining.

Plus I bet with the current, wind and stern swell you be looking at 3 knots +.

Beats rowing.

Of course then there is this option:

There has been talk about flying very large kites from big ships that would reduce fuel consumption. Seems to me that as long as the wind from astern was moving faster than the boat was moving, you'd get some propulsion from the sails and reduce your fuel use.

I bet someone smarter than me could calculate how many pounds of force are generated by a certain wind speed blowing on a square foot of flat surface.

There have been people adrift at sea for weeks. One is Adrift: Seventy-Six Days Lost at Sea.

If you have food and water to survive, drifting is all you can do and not too bad. You can relax and just let things take you wherever. Eventually you'll drift into land somewhere.

A friend of mine once sailed his broken boat several miles with his Bimini top. He couldn't steer but it got him close enough to the marina that someone saw him and towed him the rest of the way.

There was a 32' GB that used it's steady sail to sail its way home once that I read about. They even sailed through a bridge as I recall.

Turns out you don't have to be smarter than me, if I did the math right.
The formula is easy to find with a Google. A twenty mile per hour wind will create about 1 pound per square foot of force on a flat surface.

Please check my math.

I've followed Solar Sailor for years. They actually have a ferry in Sydney Harbour. The sails are sturdy, easily adjusted.

I have seen these on sailboats and don't see any reason why it wouldn't drive a trawler dead down wind.

Guys, we are going far from the subject of this thread. Let s keep it focused on Dauntless crossing the Atlantic again.

If it moves this it will certainly move a trawler. I mean think of a motorsailer sailing wing on wing. Or with a kite sail.

I think a real sailboat would be the better option. I'm an aging sailor that is considering a trawler but I am starting to think motoring my sailboat more may be the best option. On long passages there is little sail handling especially in the trade winds so sailing is not a problem. A sailboat is as efficient or more so than a FD trawler. A sailboat has the sailing redundancy. A sailboat is much more seaworthy. A sailboat has infinite range. For long range cruising, sailing is a more cost effective mode of propulsion.

...and how warm and dry is the pilothouse of your sailboat?
